1 Claim. 1

This invention relates to a ship propulsion means, and has for one of its objects the production of a simple and efficient driving means for a ships propeller, wherein the driving power is located above the water line to accommodate a minimum amount of space.

Other objects and advantages of this invention will appear throughout the following specification and claim.

In the drawing:

Figure 1 is a side elevational view of a ship, partly in section and illustrating the location of the propulsion means;

Figure 2 is an enlarged side elevational view of the propulsion means, portions of the support and encasing means being shown in section; and

Figure 3 is a sectional view taken on line 3--3 of Figure 2.

By referring to the drawing, it will be seen that ill designates the power plant or engine which is located in the engine-room l I located just below the top deck l2 of the ship l3. A driving pulley or other means I4 is driven by the engine over which passes a steel chain, or other suitable type of belt l5. This belt [5 passes over and drives a suitable pulley or other type of wheel I6 which is located just above pulley l 4, as shown.

A line shaft l! is driven by the pulley or wheel l6, which shaft l'l carries a pulley or wheel "3 at one end. A driving belt IS, in the nature of a steel chain or other suitable type is driven by the pulley l8, and this belt l9 passes over the propeller driving pulley 20 located near the bottom of the ship l3. This pulley 20 drives the propeller shaft 2|, upon which the propeller 22 is mounted.

It should be understood that the pulley 20 is smaller than the pulley l8 and that the ratio of size may vary, the pulley l8 preferably being much larger than the pulley 20. Vertically extending encasing tubes 23 extend from the top deck l2 through the engine room ll, through the space between the decks 24 and 25, the ends of the tubes 23 being anchored to the decks l2 and 25. The driving belt I 9 passes through these tubes 23 and is shielded thereby to prevent interference with the operation thereof. As shown, a housing 26 encloses the pulleys l6 and I8 and shaft I1.

49 Number Number The present device may be located in the stern of a ship to occupy a minimum amount of space and necessitate only a short propeller shaft. Because of the location of the parts, the propulsion means is readily accessible for repair and replacement and increased speed may be obtained with a reduction of fuel consumption.

Having described the invention, What claimed is:

A ship of the class described comprising a stern having an upper deck, an engine-room located just below the upper deck, said ship having an intermediate compartment below the upper deck, and a lower deck below the intermediate compartment, a power plant located in the engine-room, a pulley driven by the power plant, a second pulley located above the first-mentioned pulley, a line shaft driven by the second pulley and located above the upper deck, a driving pulley carried by the line shaft and located above the upper deck, a propeller and drive shaft located directly below the driving pulley, a pulley carried by the propeller shaft, the last-mentioned pulley and a portion of the shaft being enclosed within the ship below the lower deck, a belt passing over the driving pulley and the pulley carried by the propeller shaft, vertical encasing tubes enclosed within the ship and supporting the upper deck just below said engine room and resting on said lower deck, said belt passing through said tubes and being protected thereby, and a belt passing over the first and second pulleys for driving the line shaft.
